what physics are involved in the 100 meter dash

distance, time, velocity, acceleration. Temperature and air friction (as a force) are present also, as is the friction on the track(ever try running on ice?).

Oh yes, energy, work, and power are there also.

The 100 meter dash involves various physics principles. Here are a few physics concepts that come into play:

1. Kinematics: Kinematics describes the motion of objects without considering the forces that cause them. In the 100 meter dash, kinematics is essential for analyzing the runner's motion, including their speed, acceleration, and displacement.

2. Newton's Laws of Motion: Newton's laws explain the relationship between an object's motion and the forces acting upon it. In the 100 meter dash, the runner applies force to accelerate their body forward, overcoming inertia as described by Newton's first law. They also experience air resistance, which is especially significant at high speeds, as described by Newton's second law.

3. Friction: Friction is the force that opposes motion between two objects in contact. Although the effect of friction is usually minor during the 100 meter dash on a proper track, it still plays a role in the runner's acceleration and can affect their performance.

4. Energy: Energy is the ability to do work. In sprinting, the runner converts chemical energy from their body's stored energy sources (such as ATP) into mechanical energy, propelling themselves forward. Understanding energy principles can help analyze the efficiency and effort expenditure of the runner.

5. Biomechanics: Biomechanics is the study of the mechanics of human movement. Analyzing the sprinter's body position, stride length, foot placement, and other factors enables us to understand how they optimize their performance and maximize their speed.

To gain a deeper understanding of the physics involved in the 100 meter dash, you can explore these topics further by studying physics textbooks, articles, or online resources specifically dedicated to sports physics or biomechanics. Additionally, discussing with physics teachers, coaches, or experts in the field can provide valuable insights.
